Learning about the teams behind the platform
At TikTok, powering a safe, seamless, and personalized user experience for over a billion people around the world takes the work of many dedicated teams across engineering, data, research, and security. From building cutting-edge recommendation algorithms to safeguarding the platform from harmful content and potential threats, our teams work at the intersection of innovation, trust, and impact.
